Multicloud-Based Evacuation Services for Emergency Management

Abstract

A smart evacuation needs a scalable and flexible system to provide service in both emergency and normal situation. A single cloud service is usually limited to support scaling up requirement in emergency especially with a large geographic scope. In this article, we propose MCES, a multi-cloud architecture that deploy the smart evacuation services in multiple cloud providers, which can tolerant larger pressure than single cloud-based services. Usually, this system maintains basic service to support monitoring, while in emergency, the visits to the service will scale up enormously. This means MDSE supports fast scaling up service capacity in a short time. We use a three layer cloud instance management to support rapid capacity scaling up in MCES. By conducting extensive simulations, we demonstrate that our proposed MCES significantly outperforms single cloud solutions under various emergency settings.

Cloud-based Evacuation Services There some existing works propose prototypes that adopt cloud computing in the evacuation system. Chu et al. [1] present a hybrid building fire evacuation system with mobile phones and cloud computing. In their prototype, they put the rout computing into the cloud service and use mobile phone to get the sensor information. However, they only move the evacuation services from local to the cloud simply without any consideration about the emergency management. Chen et al. [2] present a system about rescue service with mobile cloud computing. From their work, the rescue system is similar with evacuation system which needs a rescue service to find the evacuation route and also need the information from

SPFM: Scalable and Privacy-Preserving Friend Matching in Mobile Cloud

“…Recently, there are quite a few proposals for private profile matching, which allow two users to compare their personal profiles without revealing private information to each other [4][5][6][7]. In a typical private profile matching scheme, the personal profile of a user consists of multiple attributes chosen from a public set of attributes (e.g., various interests [4], disease symptoms [8], or friends [9] etc.).…”

MEDAPs: secure multi-entities delegated authentication protocols for mobile cloud computing

“…With the emerging of cloud computing, cloud‐based applications have been booming in recent years. Many applications based on the outsourced computation have attracted the researchers and engineers from academy and industry on account of the cloud's powerful storage and computational capability.…”

Efficient keyword search over encrypted data in multi-cloud setting

“…Additionally, both Google Mail and Hotmail have experienced services down‐time which results in cloud data unavailability due to single CSP. Aiming at avoiding service failure, in such case these companies supporting cloud storage services have tried to employ multiple CSPs to ensure data availability.…”
